This SFR accesses two registers; a transmit shift register and a receive latch register.
When data is written to SBUF0, it goes to the transmit shift register and is held for
serial transmission. Writing a byte to SBUF0 initiates the transmission. A read of
SBUF0 returns the contents of the receive latch.
Read = 0b; Must Write 0b;
Baud Rate Generator Enable.
0: Baud Rate Generator disabled. UART0 will not function.
1: Baud Rate Generator enabled.
Read = 0000b; Must Write = 0000b;
00: Prescaler = 12.
01: Prescaler = 4.
10: Prescaler = 48.
11: Prescaler = 1.
